Abstract

PURPOSE:To make it possible to excavate a tunnel having a rectangular section by driving cutters arranged in a forward direction at specific intervals to reciprocate in the direction of the cutter arrangement, and introducing excavate earth from spaces between the cutters. CONSTITUTION:A shield device M is placed in the ground to arrange longer cutters in a forward direction at specific intervals in a state to press the cutters 1 against a facing, and they are operated in driving section. Face boards 10 are reciprocated up and down in the direction of the cutter arrangement, and a facing bedrock is excavated with the cutters 1. After that, excavated earth is moved backward of a taking-in device M in a chamber C from slits 11. According to the constitution, uniform excavation can be carried out.

である。In order to solve the above-mentioned technical problems, the present invention has the following configuration: Long cutters are arranged at predetermined intervals on a plane in the direction of travel, and the cutters are given reciprocating motion in the direction in which the cutters are arranged. An excavation device for the shield method is equipped with a driving part and configured to introduce the removed soil from the gaps between the respective cutters. It operates to excavate by reciprocating in the direction. Therefore, unlike a rotating cutter, there are no dead points where excavation cannot occur, and excavation can be done evenly, and earth can be easily removed.
